From f597b456c77dfca5c947e2d297efdd1d62e92b6f Mon Sep 17 00:00:00 2001 From: John Crispin Date: Sun, 22 Feb 2015 08:29:14 +0000 Subject: ipq806x: fix "reboot" command The watchdog driver already registers a restart notifier, we just have to enable it in the config and in the DT to fix the "reboot" command. This is done by integratin the following patch-set: https://lkml.org/lkml/2015/2/20/610 I'm copy-pasting the description below: qcom-wdt is currently assuming the presence of a dedicated node in DT to gets its configuration. However, on msm architecture, the watchdog is usually part of the timer block. So this patch-set is changing the driver and slightly enhancing the timer DT bindings to provide the relevant clocks and interrupts.
